Turbosynth SC 2.2 Manual Addendum

Welcome to Turbosynth SC! This upgrade offers several new features and many enhance-
ments to existing ones including integrated SampleCell II support, more playback options,
new modules, stereo capabilities, and more. Please take the time to read this Addendum to
become familiar with all these additions. Here’s what you'll find in the Turbosynth SC 2.2
Manual Addendum:

e Section 1: Getting Started gives you an introduction to Turbosynth SC, and tells you
what you’ll need to use Turbosynth SC, how to install it, and how to configure it
on your Macintosh.

e Section 2: What’s New lists the features that have been added since version 2.0.
e Section 3: What has Changed lists all other changes to Turbosynth SC since version 2.0.

e Section 4: Using SampleCell IT with Turbosynth SC explains Turbo’s SampleCell II
support and shows what a potent combination these two applications can be.

Section 1: Getting Started

What is Turbosynth SC? Turbosynth SC is software that allows you to create and manipu-
late sounds for Digidesign’s SampleCell™, Pro Tools™, Sound Tools™ and Audiomedia™
digital recording and editing systems. Turbosynth SC uses a “modular” approach to synthe-
sis, by providing a variety of modules such as oscillators, filters, and waveshapers to create
and modify sounds. This approach to synthesis has been used since the earliest days of
electronic music, when analog synthesizers were programmed using patch cords. While this
type of modular synthesis provided complete flexibility — modules could be patched in any
configuration, allowing the user to literally “design” any imaginable synthesizer architecture
— patch cords were clumsy to use and patches couldn’t be stored in computer memory.

Turbosynth SC combines the flexibility of modular synthesis with the power and conve-
nience of modern digital synthesis, sampling, sound processing and hard disk storage
technology. This combination allows you to draw on the strengths of each sound producing
method to produce the widest possible range of sounds. Once created, these sounds can be
opened in SampleCell or one of Digidesign’s digital recording systems and played back via
MIDI or from a “playlist.”

Turbosynth SC 2.2 Manual Addendum 5

What You'll Need

in order to use Turbosynth SC, the following is required:

e System 7.0 or later, in 32-bit mode, with a minimum of 5 Megabytes of RAM.
While Turbosynth SC will operate with as little as 2 Megabytes of available RAM,
we strongly recommend 8 Megabytes to take full advantage of Turbosynth SC, as
well as to be able to use some of the larger Example files.

Optional (but highly recommended) equipment includes:

e A SampleCell playback card, or any Digidesign DSP card (AudioMedia II,
AudioMedia LC, Pro Tools, Sound Tools, etc.). A SampleCell card will provide 16-
bit playback fidelity, and a DSP card will provide high-fidelity output and direct

sampling input.

NOTE: Without a SampleCell or DSP card you will not be able to use Turbosynth SC’s
Diffuser module. If you open Turbosynth documents which already contain a Diffuser,
the signal will automatically pass through the module (as if it was in a “bypass” mode).

Installing the Turbosynth SC Software

This section shows you how to install Turbosynth SC on your hard disk. We strongly
recommend you carefully follow the steps outlined below. In other words, this is not the
time to exercise your creativity — you’ll have plenty of time for that later, after you’ve
correctly installed and authorized your copy of Turbosynth SC. Turbosynth SC allows you
to authorize up to three hard disks for Turbo-use.

Important

We know, copy protection can be an inconvenience. However, the installation procedure
you’ll follow with Turbosynth SC is fast, flexible and does not require a serial number. As
long as you hold onto your master disk and follow the instructions in this section you
should be able to use Turbosynth SC without a hitch.

6 Digidesign

Please, do NOT run Turbosynth SC directly from the floppy disk. (Floppy drives are too slow
for Turbosynth SC.)

To install Turbosynth SC on your hard disk:

e Insert the Turbosynth SC Master Disk into any floppy drive.

e Double-click the Turbosynth SC icon. The following dialog box appears:

You are running Turbosynth SC™ from the master
diskette. Authorized copies can run on your hard
disk without requiring this master diskette.

Select Setup to install or remove authorization for
any available hard disk. Select Continue to run this
master copy or Quit to quit this application.

¢

e Click Setup. If you click Continue, you will still be able to install Turbosynth SC, but
you will not have authorized your hard disk. If you install Turbosynth SC without
authorizing your hard disk you will be required to insert the master disk each time
you start up the program. Therefore, don't click Continue unless you need to
somehow limit access to your installed copy of Turbosynth SC.

After you click Setup, the following dialog box appears:

Turbosynth SC™ will run on any authorized hard disk
]} without requiring the master diskette. You have a
remaining authorization count of 3.

Select Authorize to install authorization to a hard disk or
Deauthorize to remove authorization. Select Quit to quit.

| Authorize Deauthprize {quit |

e Click Authorize. The next dialog that appears lets you do two things: specify which
hard drive will be authorized for Turbosynth SC, and copy the application to the
authorized drive.

e Select the hard disk on which you want to install Turbosynth SC using the pop-up
list (in the example above, “Mac HD” is selected).

e Check Make a copy of the application on the hard disk... If you do not check this
checkbox, the selected hard disk will still be authorized, but you’ll have to manu-
ally drag-copy the application from the floppy disk later.

¢ Click OK.

A standard Macintosh file dialog box appears asking you to indicate where on the
selected and authorized hard disk you want Turbosynth SC to be installed. (We
suggest you create a new “Turbo” folder (by clicking the New Folder button) before
installing the application). Do NOT rename the application.

¢ Choose the location for Turbosynth SC and click Save.
You'll now see a couple of dialogs go by as the installer first authorizes your hard

disk, then copies the application from the floppy. When these two processes finish,
this dialog appears:

Turbosynth SC™ is now authorized to run on “Mac

HD". You have a remaining authorization count of 2.

| OK

This dialog box confirms that your hard disk is now authorized to run Turbosynth
SC, and tells you how many more authorizations your disk has left (in the example
above, the disk has a remaining authorization count of 2).

e Click OK. The following dialog appears again:

e Click Quit and, when you return to the Finder, eject the Turbosynth SC Master disk.

To learn how to “Deauthorize” your hard disk, see the following section
“Deauthorizing your hard disk.”

This completes the installation and authorization of Turbosynth SC. You can now complete
the procedure by installing the supporting files from the Turbosynth SC Miscellaneous Files
floppy disk.

You are now ready to start using Turbosynth SC! One more thing though, before you get
engrossed in Waveshaping, Spectral Inverting and Diffusing — send in your Registration
card! This will guarantee that you’re kept up-to-date with news from us about upgrades to
Turbosynth SC and other Digidesign audio production tools.

About Deauthorizing Your Hard Disk

On an Authorized hard disk, you can start up, use, and even move Turbosynth SC around
without ever being prompted for your master disk. If you use up your three authorizations
(reinstalling Turbosynth SC after a hard disk crash, etc.), no additional authorizations can

occur until you “reclaim” an authorization by using the Deauthorization feature of the
Turbosynth SC installer.

To Deauthorize your hard disk:

e Insert the Turbosynth SC Master disk into any floppy drive connected to the hard
disk that you want to deauthorize.

¢ Double-click on the floppy disk icon to open it.

° Double-click on the Turbosynth SC on the master disk to launch the installer.

If you have not already done so, be sure to open and read the Read Me! file on your Misc
Files disk. The Misc Files disk contains a few system utilities which your computer might
need — the Read Me! will tell you whether or not you need any of these files. If you have
any problems or questions about installing, authorizing or deauthorizing Turbosynth SC,
try repeating the steps listed above. If you have tried and still have problems, call Digidesign
Technical Support at (415) 688-0744

Audio Connections

The ideal audio configuration for Turbosynth SC is to use Digidesign’s 32-voice, 32 Mega-
byte SampleCell II sample playback system for audio playback. Turbosynth SC can also play
audio through any Digidesign DSP card (Pro Tools, Sound Tools, Audiomedia, etc.). If you
do not have either of these, you can use the Macintosh internal speaker to hear your
sounds.

If you plan to use SampleCell or another Digidesign DSP card, connect your card’s audio
outputs to your mixer and/or other audio gear. Turbosynth SC files can be either mono or

stereo, sO be sure you use two outputs of your audio card for true stereo playback.

This completes the basic installation process. You are now ready to start using Turbosynth SC.

Section 2: What's New

This section tells you what new features you will find in Turbosynth SC. Features added
since version 2.0 are included for those of you who have not upgraded to version 2.1.

Copy Protection

This one should be obvious if you just completed the installation instructions. You must
have a Turbosynth Master disk to start-up Turbosynth SC. The installation instructions
contain everything you'll need to know about Turbosynth SC 2.2’s copy protection.

Turbosynth SC 2.2 Manual Addendum 17

Playback Options

Turbosynth SC is compatible with all of Digidesign’s DSP cards (Pro Tools, Sound Tools II,
Audiomedia II). There are two new Options menu commands, Playback Options and Hard-
ware Setup, which you use to configure playback for Turbosynth SC. Playback Options lets
you choose one of three possible playback configurations — a Digidesign DSP card,
SampleCell, or Sound Manager.

Stereo Documents and Stereo Sampling
Turbosynth SC reads and writes Sound Designer II and AIFF files in mono or stereo.

A stereo sample module is represented by two modules representing each channel. Both
modules are linked together so that any changes or edits in one module affect both mod-
ules. When selecting one of these modules the other is also selected. You can unlink them
using the Convert Stereo Sample to Dual Mono command in the Edit menu.

A Stereo Sample

If the document is stereo there will be two output jacks. The two output modules will share
the same loop markers, unless there is no sound data in one of the outputs. Because each
output’s sound buffer length can be different, a loop is constrained by the shorter of the two
lengths. Also, reducing the length of one output’s sound buffer may cause a deletion of loop
markers for both outputs if the marker is beyond the new length of the sound buffer. Unlike
the stereo sample modules, crossfade looping is done explicitly for each output module.

A Stereo Output Module

In the Options menu you will find the Stereo Preferences command. This command opens
the Creating Stereo dialog box, which lets you set various preferences for creating, saving and
playing stereo files in Turbosynth SC:

Turbosynth SC 2.2 Manual Addendum 13

Stereo Preferences “Creating Stereo” dialog

- Open A New Document As A. Sets the default for new documents to be Mono or
Stereo. When set to Mono Document, all new Turbosynth documents will have a
mono output jack. When Stereo Document is selected, all new Turbosynth docu-
ments will have a stereo output jack.

- Open a Stereo Sound file. With Open both channels checked, Turbosynth will auto-
matically load both channels of a stereo sound file. With Open specified channel
checked, Turbosynth will ask you to specify which channel (right or left) to load.

- Direct Sampling. Sets the default for mono or stereo direct sampling.

- Empty Sample Module. Sets the default type (stereo or mono) for new Sample
modules.

- Matching Channel Length. Sets how you want channels of differing length
“matched” in stereo files, by lengthening the shorter of the two (Pad shorter length
channel) or shortening the longer of the two (Truncate longer length channel).

14 Digidesign

- Stereo to Mono. Sets the default for whether or not Turbosynth scales a soundfile
when saving a Stereo output as a mono file, or when playing back through Sound
Manager.

- Sample Rate. Let’s you set how Turbosynth resolves sample rate differences between
the two output channels. Choices include Use highest, Use lowest, Use left channel’s
and Use right channel’s.

Memory Indicator

The main window’s info icon (in the tool palette) is now used as a memory indicator. It fills
with black from the bottom up as memory is used. In extremely low memory situations, the
word Lo! will appear at the top of the icon. When this occurs, try the following two things:
open the Info Box and click the Compact Memory and/or Release Clipboard button, or
increase Turbosynth SC’s Finder memory allocation.

Diffuser Module

The Diffuser accepts one input and provides the ability to “smear” a signal over time. The
Diffuser can be thought of as a fundamental building block of reverb.

important
The Diffuser module performs extremely complex math-intensive operations. For this
reason, you must have a Digidesign card such as a Pro Tools, Sound Tools, Audiomedia or
SampleCell card installed in your Macintosh in order to use this module. If there is no such
card physically installed in your CPU, the Diffuser icon will be disabled.

Turbosynth SC 2.2 Manual Addendum 15

The Diffuser

The Coarse and Fine sliders control the amount of diffusion, or “smearing.” The Amount
slider controls the relative level of diffused signal to dry signal. 0% results in no audible
effect, 100% results in full effect.

Convert to Oscillator

In addition to the Convert to Waveform command, Turbosynth SC offers a unique capability
to convert an entire sample into an oscillator.

To convert a sample into an oscillator:
e Select the sample module in the work area of the Main Window.
e Choose Convert to oscillator from the Edit menu.

The following dialog box appears:

This will convert the currently selected
7 sample module into an oscillator. It
4 might take a while. No can “Undo".

| Extract a waveform every ms t

} Fundamental frequency: 220.000 | Hertz

| (J Track frequency changes

!

Convert to oscillator dialog box

16 Digidesign

“Extract a waveform every” will tell Turbosynth SC how many waveforms you want
the sample broken into. The higher the number you enter here, the more closely
the resulting oscillator will resemble the original sample. The lower the number
you enter, the less recognizable the result. Experiment with different extraction
values to find what works best for you.

The Fundamental Frequency is the fundamental pitch the oscillator will sound.
Change this value to change the pitch of the sound before it is converted to an
oscillator.

Track frequency changes lets Turbosynth SC create multiple waveforms with differ-
ing fundamental frequencies when converting complex samples into oscillators.
Leave this option off to get an oscillator that doesn’t deviate from its fundamental
frequency.

e Set the parameters in the dialog box as appropriate and click OK.

This operation can take a few moments. When conversion is finished, your screen will
return to the Main Window, and the module which you just converted will appear as a
waveform icon.

Windows menu

A Windows menu has been added. This menu lists all currently open Turbosynth SC
document and/or module windows. Choosing an item from the Windows menu makes that
window the “topmost” (i.e., active) window.

Monitor Loop at Output

Located in the Parameter Manager dialog box (accessed via the Options menu), the checkbox
Monitor Loop at Output provides some flexibility for listening to looped Turbo sounds. When
checked, you can use the normal play functions (space bar, clicking the speaker) from the
main window and hear the loop (if you have set loop start and stop points). If unchecked,
you will only be able to hear the loop from within the Loop Window.

Turbosynth SC 2.2 Manual Addendum 17

Section 3: What has Changed?

The following are some of the more significant changes that have been made to Turbosynth
SC since version 2.0. Consult the Turbosynth SC 2.2 Read Me! document for any additional
changes.

¢ Mac- Sampler, Sampler- Mac commands are no longer supported.

e The Tab key of your computer keyboard toggles between the Arrow, Patch Cord
and Eraser tools.

e The File menu command Save Output as soundfile has been replaced by the two
commands Save Output, and Save Output As. These two commands function
similarly to the familiar Save and Save As commands of many Macintosh applica-
tions, and have specific uses when using Turbosynth SC with SampleCell II. Refer
to Section 4 for more information.

e Select All now works in the Oscillator window (to select all waveforms) and in the
Sample Module (to select the entire sample) as well as in the main window.
Previously, Select All only worked to select all modules placed in the work area.

Section 4: Using SampleCell Il with Turbosynth SC

Introduction

If you already use SampleCell, chances are good that at some point you have used Sound
Designer II SC™ to modify a sample you’re using in a SampleCell Instrument. If you are
new to SampleCell, or have never used Sound Designer II SC in this fashion, suffice it to say
that switching between these two applications is so easy it makes Sound Designer II SC and
SampleCell work almost as if they were two windows of a single application.

Digidesign

In a somewhat similar fashion, Turbosynth SC can be used as a sound editing extension of
SampleCell. The way it works is like this: come up with a sound in Turbosynth SC, turn on
Auto Update SampleCell, and then save your Turbosynth SC sound as an Output file.
SampleCell will automatically create a new Multi-Sample Instrument and load the sound in
the output file into it. If your Turbosynth SC sound is a stereo sound, SampleCell will create
a Stereo Multi-Sample Instrument, automatically!

If you want to continue creating new Instruments, simply Save Output As (to save a different
version of the Turbosynth SC sound). SampleCell will load each output file as a new
Instrument.

Once an Output file is in an Instrument it can be modified in Turbosynth SC, and automati-
cally updated in SampleCell II, by doing a Save Output. This updates the saved-to-disk
Output file, and SampleCell then updates itself with this new version of the file.

For multi-sampling, the process is slightly different due to the fact that the goal is to create
Multi-Sample Instruments rather than single-sample instruments. Refer to the section Working
with Multi-Sample Instruments later in this appendix for more information.

Before you begin
e Make sure your SampleCell card(s) are installed correctly and operating properly.

e This section assumes you have a working knowledge of SampleCell, and are
familiar with SampleCell Instruments, Banks, Keygroups, Velocity Zones, etc. If you
are not familiar with these terms, you might end up a bit confused by this section.
You must understand the basic operation of SampleCell before proceeding.

You’te ready to start hearing what you can do using the combination of Turbosynth SC and
SampleCell!

Turbosynth SC 2.2 Manual Addendum 19

Getting Started

Setting up the link between Turbosynth SC and SampleCell is easy. Here’s how to get the
pair working together quickly: |

To setup Turbosynth SC and SampleCell links:

¢ Open Turbosynth SC and open a sound or create a sound from scratch. This will be
the first sound of your SampleCell Instrument.

e Once you’ve got your sound, choose Auto Update SampleCell from the Options
menu. This “turns on” the link between the two applications.

e Choose Save Output from the File menu of Turbosynth SC. A Macintosh save file
dialog appears. Name the output file, select a destination folder and indicate the
desired file format (Sound Designer II, Sound Designer, or AIFF).

When the output file is saved, SampleCell automatically loads it into a new multi-
sample instrument (SampleCell will automatically launch, if it is not already
running.) If you want, switch to SampleCell and adjust instrument parameters, or
remain in Turbosynth to further edit the sound:

To edit the sound in Turbosynth SC after it is in SampleCell:

e Modify the sound.

¢ Choose Save Output from the File menu. Just like the familiar Save command found
in word-processors, this command updates the earlier output file with the modifi-
cations you have just made. At this point, Auto Update SampleCell tells SampleCell
to load this newest version of the sound, replacing the original but retaining its
keygroup, velocity zone, or other SampleCell parameters. Remember, if you do Save
Output As, SampleCell will create a whole new single-sample instrument with the
new output file instead of updating the existing one.

20 Digidesign

Working with Multi-Sample Instruments

You can take advantage of Auto Update SampleCell with multi-sample instruments as well.
Here’s how you should go about creating, and then working with, an instrument contain-
ing multiple Turbosynth SC sounds:

To use multiple Turbosynth SC sounds in one multi-sample instrument:
e In Turbosynth SC, turn OFF Auto Update SampleCell.

e Open your first sound and modify it, if necessary. (Be sure to play the sound so
that the signal is present at the Output module.)

e Choose Save Output from the File menu. Name the output file and indicate a
location for it.

e Continue in this manner, opening other sounds or modifying your first sound, and
use the Save Output As command to save each variation until you have enough raw
sounds to use in SampleCell (how many is “enough” is completely up to you).

e Next, launch SampleCell and create a new, Multi-Sample Instrument. (When
you're ready to be a power user, turn Auto Update SampleCell back on before
saving your last output file. As described earlier, this will launch SampleCell, create
a multi-sample instrument, and load this output file automatically. You would
then move to SampleCell and continue as described below.)

e Open the Sample Map window for your new Instrument and click the New Keygroup
button. SampleCell’s Select a file to open dialog appears.

¢ Locate and load the output file(s) you just created in Turbosynth SC as your first
keygroup, then continue adding new keygroups or velocity zones as described in
your SampleCell User’s Guide. Adjust the keygroup and velocity zone boundaries as
you normally would, and, if you like, audition them with your MIDI controller.

You should now have the basic elements of your Instrument in place. It is likely, however,
that you will want to edit your sounds further after hearing them in your instrument. Here’s
how you can take advantage of Auto Update SampleCell for this:

Turbosynth SC 2.2 Manual Addendum 21

To edit multi-sample instruments:
e First, save the Instrument (and the Bank), but do not close or quit SampleCell.

e With SampleCell still running, and with your new Instrument still loaded, switch
back to Turbosynth SC.

e In Turbosynth SC, choose Auto Update SampleCell from the Options menu.

e Open and modify the sounds as needed, and save the new versions using the Save
Output command. As described earlier, SampleCell will automatically update itself
with these new versions of your sounds.

That covers the basics of using Turbosynth SC with SampleCell. There are, however, several
Preference settings within SampleCell which can speed up a few of the above tasks. These
options include:

¢ Make One Instrument when multiple sound files are dragged onto the editor. As a
shortcut to launch SampleCell II you can drag and drop individual or multiple
sound files onto the SampleCell Editor application. When a single sound file is
dropped on the Editor, SampleCell will automatically create a single-sample
instrument with that sound as it launches (no need to click Load, then locate and
open the individual sample). When you drop multiple sound files (perhaps a folder
of S or 6 Turbosynth Output files) SampleCell will create that number of single-
sample instruments, unless this Preference is On. When On, SampleCell will load
all the dragged-and-dropped sound files into a single, multi-sample instrument
automatically.

e Default new single sample instruments to Key Track OFF. This Preference tells
SampleCell to keep Key Track Off for all new single-sample instruments. Having
key track off is often desirable for sound effects or other instances where pitch is
irrelevant. Generally, if you have a sound in Turbosynth SC that you want to hear
transposed across the entire keyboard, you would probably not want to have this
Preference On.

e Automatically remap Instruments in a bank after adding an instrument. This command
spreads all existing instruments in the current bank over a 5 octave range (i.e. sets
hi/lo MIDI notes), and sets the first samples base note to the center of the range.
For example, if you have 5 instruments open, the leftmost instrument will be
mapped from C0 to B2 with its root note set to F#2. Moving to the right, the next
instrument will be mapped from C3 to B3 with a root note of F#3, and so on.

By configuring these Preferences to match your work habits, your Turbosynth SC/
SampleCell system can be optimized for maximum efficiency.

Don’t forget, if you have a Digidesign DSP card (Pro Tools, Sound Tools or AudioMedia) and
the requisite audio interface, you can direct-sample into Turbosynth’s Sample module as a
way to collect raw samples for your system.
